Windows 7 freezes randomly within 30 seconds of start up or as much as 10 hours. No specific programs seem to cause the crash. I usually play games for hours without problems, but outside of games generally on smaller programs like Firefox or the Steam browser. I have had this problem on both 32-bit Home and Professional with the same consistency, both on this computer. I have updated all my drivers, however I have not tried to update my BIOS. Hardware: Motherboard - Biostar, GeForce 6100-M9 v1.1 Processor - AMD, Athlon 64 X2 3800+ Video Card - NVIDIA GeForce GTS 250 RAM - 3Gb Thanks.
